In 1978, Yamashita launched the career of then 24-year old Murata after the promising singer-songwriter submitted his demo tape to RCA Records. He started off as a backing singer for Yamashita and in 1982 debuted as a soloist. Like his mentor, Murata has also been influenced by popular American music of the 60’s, though a number of his other songs also showcase his rock roots since he's been a fan on Cream and Led Zeppelin since junior high school. I can hear that side of him through the vocals in some parts of “Ippon no Ongaku”, particularly the bridge leading up to the refrain, though the song itself is largely a pop piece. As for the rest of the credits, it was written by Yoshihiko Ando (安藤芳彦) and composed by Murata.
